1930SummerGustav SHanson found an osprey's nest near Deer River, on June 4th, which contained an undetermined number of eggs.
1932Summer3 nests were located, all with young birds, the first at Deer River by Frank Zoubek in the last week of June, and the latest at Lake of the Woods by Gustav Swanson on August 26. Tho latter nest was in a live spruce, a very unusual focation for this bird, which generally nests in dead trees.
1933Summer But one nest of tho Fish Hawk was observed this year, and that by Risse:r at Sturgeon Lake. That worthy gentleman sallied fortht as was his wont, on June 30th and hied himself to tho nost, wondering how it had fnrod a storm of the previous night. We can visualize tho look of chagrin that crept over his cotmtonp.nco when arriving at the spot, he found two broken eggs on the ground. While it would probably not prove especially bcnoficia.1 to tho owners, the ability nf conjuring up a. storm of sufficient intensity would seam to be a vory convenient moans of ascertaining the contents of ordinarily inaccessible eryies.
1934Summer The first nest of this species w~s reported by H;i.cmonz, vrho found it on June 9th near Cross Lake. Three eggs nestled in its lofty bosom. Morse and Feeney found the last nest at Ita.sca Park on July 31st, when it held "one, :perhaps more, nearly full-gro"Ym young. 11
1937SummerM. Morse located a nest, July 8, at Cloquet Valley Forest. Con­tents of the nest unknown. On July 10, D. Struthers found three nests at Ver­million Lake..
1938SummerAt Lake Vermillion on Au­ gust 2, D. Struthers discovered a nest with 2 young Fish Hawks.
1940SummerTwo young birds were ob­ served leaving the nest on July 24, at Lake Vermillion by K. Carlander. This was the only record for the fish hawk.
1944SummerJuly 29, two young, Hub­bard County, Whitney Eastman.
1961SummerR. Grant reports a pair at Clearwater County. Dave Pearson found a nest with three young at Many Point Scout Camp, Becker County, during week of 20-25 August.
